Is this coming to your town or city next? It has pluses and minuses, but it still is fairly new. San Francisco had this option for years, with some success, I am not sure if it is still going on. In the USA we have had community security for years, some with success, many had to go out of business. The first time they got hung up in a legal situation, and the cost of just defending themselves bankrupted them. Still keep your eyes on how this goes, it is an option, than more and more are looking at.
